#Army corps of engineers flexible pavement design software manual#

This manual is limited to Army airfield pavement design requirements for aircraft during a mobilization situation. A rigid pavement is considered to be any pavement system that contains as one element portland cement concrete, either nonreinforced or reinforced.Д«. The design procedures presented herein apply to the following types of pavements, design loadings, and design parameters.ДЄ. This manual presents mobilization procedures f~r the design of Army airfield rigid pavements and overlay pavements that incorporate a portland cement concrete layer in either the overlay or base pavement.ДЎ-2.

Work items not immediately necessary for the adequate functioning of the facility should be deferred until such time as they can be completed without delaying the mobilization effort.ДEPARTMENT OF THE ARMY U. Lesser grade materials should be substituted for higher grade materials when the lesser grade materials would provide satisfactory service and when use of higher grade materials would extend construction time. Time-consuming methods and procedures, normally preferred over quicker methods for better quality, should be de-emphasized. Hence~ rapid construction of _a facility should be reflected in its design. Design and construction of mobilization facilities must be completed within 180 days from the date notice to proceed is given with the projected life expectancy of five years. These requirements may be altered when necessary to satisfy special conditions on the basis of good engineering practice consistent with the nature of the construction. Criteria and standards presented herein apply to construction considered crucial to a mobilization effort. This manual is applicable to all field operating activities having mobilization construction responsibilities.ДЈ.
